This study aims to assess the overall impact of vocabulary development interventions on cognitive vocabulary outcomes. To achieve this, 43 theses on vocabulary teaching, each involving a specific intervention, were analyzed using meta-analysis. The findings from the meta-analysis, based on the random effects model, indicated that the average…

This paper details a literature review of mathematics vocabulary intervention studies for students with mathematics difficulty. The primary aim was to identify instructional practices that support mathematics vocabulary development. We conducted a database search to identify mathematics intervention studies either focused exclusively on vocabulary…

There are few published estimates of vocabulary sizes amongst students in tertiary education. Research does not offer estimates of the vocabulary size tertiary students might be expected to possess, though estimates exist for K-12 education, some EFL contexts, and the general population. Such research is important. For reading comprehension during…

Although development of young children's vocabulary knowledge is critical for their literacy, it often is neglected in classrooms, especially those pressed for time. In this article we explore a literacy coach's implementation of SAIL (Survey, Analyze, Interpret, Link), an instructional framework that integrates academic vocabulary (AV)…

The purpose of this quasi-experimental study was to investigate the use of specific vocabulary instructional strategies during a six-week summer program to determine if the iReady universal screener measured an impact on student vocabulary and reading comprehension. The study utilized a treatment group (n = 34) and a control group (n = 40) from…

This study examined preschool teachers' fidelity in implementing a vocabulary intervention. The purpose of the study is to inform the scaling up of vocabulary interventions, identifying strategies that are both feasible for teachers and effective for vocabulary learning. We analyzed data from a vocabulary intervention in which teachers (n = 10)…

Vocabulary plays a critical role in later reading achievement of emergent bilingual children (EBC) who are learning two languages. Given emerging vocabulary intervention research for EBC, we synthesize studies on vocabulary interventions designed for preschool and kindergarten EBC to provide the cumulative knowledge on the following dimensions:…

The process of learning to read is more difficult for English language learners (ELLs) because they are often learning a new language as they are trying to learn to read. Learning irregular/high-frequency words (sight words) may be especially challenging for ELL students. Limited research exists on the effects of interventions designed to help ELL…

More research attention and implementation support are needed for mathematics intervention as student achievement in this area continues to fall below desirable levels. Incremental rehearsal is an intervention to help students build reading, vocabulary, and math fluency. Research supports the use of incremental rehearsal for improving math fact…

Although much is known about supporting preschoolers' alphabet knowledge, less is known about instructional moves that support preschoolers' narrative comprehension or how preschoolers' developing cognitive skills may support their narrative comprehension development. This school-university partnership project examined relations of preschoolers'…

Many children with developmental language disorder (DLD) have a vocabulary deficit. One of the most effective interventions for increasing children's lexicon size is the semantic and phonological approach, an approach that has been used mainly with adolescents. The goals of our study are (1) to test whether the semantic-phonological approach…

This study investigates the effects of combining blooket games with active learning to improve Chinese vocabulary memorization in first-year Chinese Language Teaching students at Rajabhat Mahasarakham University. This approach aimed to make learning more engaging for Thai students. The intervention involved 26 participants and vocabulary…

This best-evidence synthesis appraises the design and outcome characteristics of vocabulary intervention studies conducted with preschool through 6th grade emergent bilingual (EB) children and spotlights rigorously designed studies for which effects could be better attributed to instructional features. Twenty-nine selected studies were analysed…

This study explored the strategy use of 12 high-school learners of English within a vocabulary teaching intervention which exposed three groups of learners to one of three types of oral vocabulary explanations: L2 explanations; codeswitched explanations (CS); and contrastive focus-on-form explanations (CFoF) giving cross-linguistic information.…

The purpose of the current study was to examine the dosage and fidelity of EMT en Español strategies that are posited to drive change in child outcomes. The study is a re-analysis of data collected during the National Institutes of Health (NIH) R21 grant "Teaching Spanish-speaking Caregivers to Implement EMT en Español: A Small Randomized…
